Fans heading for the T In The Park festival today are being warned to leave extra time for travel following the terror attack in Glasgow last weekend.

Organisers at the event in Kinross, Scotland, have introduced beefed-up security measures which they say may result in some delays for revelers trying to get into the site.

Advice posted on the festival website says: "We have taken into account recent events and have reviewed all of our practices and realigned these where appropriate to ensure that safety is paramount as always.

"These increased security measures could result in some delays when arriving at the event, particularly at the car parks and entrances and we would ask all the fans to be patient and bear with us.
